The viscosity of natural gas has considerable theoretical and practical significance in the design and operation of gas transportation, production, and processing. In order to quickly and cheaply obtain the viscosity data of natural gas, an alternate predictive model was developed based on corresponding states and Lennard-Jones averaged intermolecular potential field. Then, the accuracy of the model was assessed with 2389 experimental data points from 15 natural gas specimens after 2000, which sat in temperature and pressure ranges: 241–454 K,...
